LOOSE-LEAF BINDER.

To all whom it may concern Be it known that I, WVILrRnn CnAnLns TRAHER, a subject of the King of Great Britain, and a resident of London, in the Province of Ontario and Dominion of Canada, have invented a new and Improved Loose-Leaf Binder, of which the following is a full, clear, and exact description.

My invention has for its object to provide a loose leaf binder with few parts which may be manufactured at very low' cost and which may be readily assembled.

Still other objects of the invention will appear in the following complete description, in which the preferred form of my invention is disclosed.

In the drawings, similar reference characters refer to similar parts in all the figures, in which a Figure 1 is a perspective view showing a portion of a binder provided with my i1nprovements; Fig. 2 is an end view of Fig. 1; Fig. 3 is a view similar to that shown in Fig. 2 but with the hooks in open position; Fig. 4: is a rear view showing the plates which hold the hooks, parts being broken away to show how the hooks are secured in place; Fig. 5 is a cross sectional View of one of the plates shown in Fig. 4K; Fig. 6 is a plan view of the spring plate;

Fig. 7 is a fragmentary perspective view of 7 one of the plates shown in Fig. i; Fig. 8 1s a perspective View of one of the wires having the bent terminals which form the hooks; and Fig. 9 is a fragmentary view showing the relative positions of the hook plates.

As my loose leaf-book is constructed, it is possible to manufacture the covers rapidly and complete before the locking hooks are secured in place. The covers may be passed through rollers in the last stages of manufacture which could not be done if the hooks were secured to the covers before the manufacture of the covers was completed. The plates for the hooks are corrugated, which permits of theirmanufacture of very cheap metal, wires being provided, the central portions of which are clamped by the plates with the terminals of the wires bent to form hooks. Each of these corrugated plates has bent spring flanges, which engage thecompanion plates for holding the plates in position when their outer edges are slid within the flanges of a spring plate which Specification of Letters Patent.

is secured to the covers after the manufacture of the covers has been completed.

By referring to the drawings, it will be seen that two hook plates 5 are provided, each of these hook plates having an upwardly bent portion forming a groove 6 in its under side, there being two openings 7 in each of these plates at the grooves 6, so that the central portion 8 of a wire member 9 may be disposed in each of the grooves 6 with the terminals 10 projecting upward through the opening 7 to form the hooks 11. The inner portions 11 of the hook plates 5 between the openings '7 are bent under the central portions 8 of the wires 9 to hold the wires 9 in position relatively to the plates 5. The hook plates 5 beyond the opening 7 have on their under edges hook shaped spring flanges 12 which embrace the inner edges of the companion hook members 5, and which extend up in the grooves 6 of the hook plates 5, the hook plates 5 being articulated together by this means, which also serves to limit the movement of the hooks 11 away from each other, for it will be seen that when the hook shaped spring flanges engage the inner sides of the grooves 6, the movement of the hook members 11 away from each other is retarded by the resiliency of the spring flanges. These hook members 5, with the hooks 11 mounted thereon in the manner described, are held by a spring plate 13 by the engagement of the flanges 14 of the spring plate 13 with the outer edges 15 of the hook plates 5. When the hook plates 5 have been constructed and have been articulated together in the manner described, they are slid into position within the flanges 14E of the spring plate, as shown in Figs. 1, 2, 3 and a of the drawings. The spring plate 13 is secured to the cover member 16 by means of the rivets 17 or in any other approved manner. There are cuts 5 in the hook plates 5 which serve to give the flanges 12 the desired resiliency.

The applicant does not wish to limit himself to the embodiment of the invention shown in the drawings, for in the manufacture of the binder he may find it advisable to use spring flanges at the center of the hinder or to shorten the slots 5 Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In a device of the character described,

two wires having central portions and bent terminals forming hooks, two plates articulated together and having portions bent around the central portions of the wires, and

a spring plate having flanges for engaging and holding the outer edges of the first plates.

2. In a device of the character described, two wires having central portions and terminals bent to form hooks, two plates with openings spaced apart and articulated together, the plates having inner portions bent around the central portions ofthe wires, with the hooks extending up through the openings in the plates, and a spring plate having flanges for engaging and holding the outer edges of the first plates.

3. In a device of the character described, two wires having central portions and terminals bent to form hooks, two companion plates, each having two openings with their inner portions between the openings bent 7 around the central portions of the wires,

with the hooks extending up through the openings, a bent flange on the inner side of each of the plates, the flanges engaging the inner sides of the companion plates and a spring plate formed with flanges for engaging and holding the outer edges of the first mentioned plates.

4. In a device of the character described,

two wires having central portions and t'er' minals bent tOsfOllIl hooks, two plates, each having a groove in its under side adjacent its inner edge, there being two openings in each of the plates at the grooves, the central portions of the wires being disposed in the grooves between the openings with the hooks disposed up through the openings,

flanges on the plates bent up and extending into'the grooves in the companion plates beyond the openings therein, and a spring plate having flanges for engaging and holding the outer edges of the first mentioned plates.

5. In a device of the character describec, two plates, a hook secured to each of the plates, there being grooves in the under side of the plates, and flanges on the plates extending up into the grooves in the companion plates, and a spring plate for engaging and holding the outer edges of the first plates.

6. In a device of the character described, two wires having central portions and terminals bent to form hooks, two companion plates, each having two openings with their lnner portions between the openings bent its inner edge, there being two openings in each of the plates at the grooves, the central portions of the wires being disposediin the grooves between the openings with the hooks disposed up through the openings, spring flanges on the plates bent up and extending into the grooves in the companion plates beyondthe openings therein, and a spring plate having flanges for engaging and holding the outer edges of the first mentioned plates. p V r 8. In a device of the character described, two plates, a hook secured to-each of the plates, there being grooves in the under side of the plates, spring flanges on the plates extending up into the grooves in the compan-i ion plates, and a spring platefor engaging and holding the outer edges'of the first plates. I. I l

9. In a device of the character described,

two wires having central portions and terminals bent to form hooks, two plates disposed side by side, each having-a groove in its under side adjacent its inner edge, there" being two openings in each of the plates at the grooves, the central portions of the wires being disposed in the grooves between the openings with the hooks disposed up through the openings and means engaging the outer edges of the plates for holding the plates in operative position. 7

10. In a device of the character described,

two plates, a hook secured to each of the 7 plates, there being grooves inv the underside. of the plates and flanges on the plates eX- tending up in the grooves of the companion plates for articulating the plates together and resilient'means for holding the plates yieldingly relatively to each other.

In testimony whereof I have signed my name to this specification in the two subscribing witnesses.
